Microsoft's Windows Phone platform has reached a 9.2 percent share in the smartphone operating system (OS) market in European markets, driven by Nokia's models, market research firm Kantar said on Monday.

Smartphone sales data from Kantar Worldpanel ComTech, for the three months to August 2013, shows Windows Phone has posted its highest ever sales share of 9.2% across the five major European markets (Great Britain, Germany, France, Italy and Spain) and is now within one percentage point of iOS in Germany.

Android remains the top operating system across Europe with a 70.1% market share, but its dominant position is increasingly threatened as growth trails behind both Windows and iOS, the research firm said.
